Flutter app development
Keepport builds Flutter apps for US small businesses: one Dart codebase that compiles to native iPhone and Android apps, from $3,000, in six to ten weeks. Flutter is Google's toolkit and our choice for apps with rich animation, custom design or a kiosk and web version that should share code, such as gym check-in screens, salon booking with visual calendars and church apps with media players.
What's included
Same tiers as every Keepport build, scoped and quoted before we start. We choose Flutter or React Native per project; you never pay more for either.
- One Flutter codebase, two native apps, optional web or kiosk build
- Custom, pixel-exact design on both platforms
- Native platform channels where a feature needs them
- Null-safe Dart, tests on the payment and booking flows
- Design in your brand, admin dashboard, one integration
- App Store and Google Play submission
- Care starts the day you launch — the first 60 days are included
Not included
- Store fees, third-party API costs, hosting after month one
